Is There A Way To Reverse The Formatting By Intl Numberformat In Javascript

Absolutely, there is a way to reverse the formatting by Intl NumberFormat in JavaScript! If you've ever needed to convert a formatted number back into its original raw value, this guide will walk you through the process. Let's dive in!

The Intl NumberFormat object in JavaScript provides a way to format numbers based on the locale settings. It allows you to display numbers in a user-friendly manner with proper symbols, separators, and decimal points. However, converting a formatted number back to its original value might seem tricky at first glance, but fret not – it's totally doable.

To reverse the formatting by Intl NumberFormat, you'll need to follow a few steps. First, you'll have to create an Intl NumberFormat object with the desired locale and formatting options. Next, you can use the object's "formatToParts" method to parse the formatted number into its individual parts, such as integers, decimals, and symbols.

Here's a simple example to illustrate this process:

const formatter = new Intl.NumberFormat('en-US', {
  style: 'currency',
  currency: 'USD',
});

const formattedValue = formatter.format(12345.67);
console.log(formattedValue);

const parts = formatter.formatToParts(12345.67);
const originalValue = parseFloat(parts
  .map(part => part.type === 'fraction' ? `.${part.value}` : part.value)
  .join('')
);

console.log(originalValue); // Output: 12345.67

In this example, we first create an Intl NumberFormat object with the locale set to 'en-US' and currency formatting for USD. We then format the number 12345.67 using this formatter and store the result in the "formattedValue" variable.

To reverse the formatting, we use the "formatToParts" method to break down the formatted number into its parts, including the integer and decimal components. By iterating over these parts and reconstructing the original number, we can obtain the raw value – in this case, 12345.67.

Keep in mind that the approach may vary depending on the formatting options used in your Intl NumberFormat object. You may need to adjust the parsing logic based on your specific requirements, such as handling different locales, number styles, and currency formats.

By understanding how to reverse the formatting by Intl NumberFormat in JavaScript, you can enhance your data processing capabilities and build more versatile applications. Experiment with different formatting options and explore the flexibility offered by the Intl API to tailor number display to your users' preferences.

In conclusion, reversing the formatting by Intl NumberFormat in JavaScript is achievable with the right techniques. Utilize the formatToParts method and parsing logic to extract the original value from a formatted number effortlessly. Armed with this knowledge, you can confidently manipulate formatted numbers in your JavaScript projects with ease. Happy coding!
